Questions about this item

What does the 8200 MT/s DDR5 figure mean once the board and CPU are installed?

With the included Ryzen 7 9800X3D the four DDR5 slots can run memory up to 8200 MT/s when overclocked, delivering high bandwidth for gaming and AI workloads.

How does the PCIe 5.0 interface cap graphics and storage performance in practice?

The top x16 slot and the first three M.2 slots use PCIe 5.0, so a modern GPU and up to three PCIe 5.0 SSDs each get full x4 or x16 bandwidth without sharing lanes.

What does the ATX motherboard physically need to fit and mount in a case?

The board follows the standard ATX layout with 288-pin DDR5 slots, four SATA ports, five M.2 sockets (2242, 2260, 2280) and rear I/O including two USB4 Type-C ports, so any ATX-compatible case and PSU with 24-pin plus 8-pin CPU power will accommodate it.
